Amorphous optical coatings of present gravitational-wave interferometers*
Abstract We report on the results of an extensive campaign of optical and mechanical characterization of the ion-beam sputtered oxide layers (Ta 2 O 5 , TiO 2 , Ta 2 O 5 –TiO 2 , SiO 2 ) within the high-reflection coatings of the Advanced LIGO, Advanced Virgo and …
